All Implemented Interfaces:

java.io.Serializable, StandardBean, FocusedContext, MultiFocusedContext, ViewContext

public class DefaultMultiFocusedContext
extends DefaultViewContext
implements MultiFocusedContext

Convenient base class for multi-focused contexts. The single focus multi-focus behavior is such that if there are multiple objects with focus then getFocus() returns null.
